oxL-connuo'ron.

To all whom it may concern:

- Be itknown that I, Jorm 1110mm) Dori-- ivnrmga citizen of the United States, resi ding at Portland, in the county of Cumberland sand State of Maine, have invented certain new and useful Improvements in Oil-Conductors.

cation.

This invention relates to oil conductors and particularly to a flexible oil conductor adapted to be used in connection with oil consuming apparatus such as torches, lamps and other devlces using hydrocarbon or any similar liquid fuel. It has been found necessary in these conductors to use only metal in contact with the oil and it is the object of the present invention to provide a conductor which will have only metal surfaces contacting with the oil, which will be flexible and at the same time protected against undue twistor compression which mightrupture or dent the thin metal of the inner tubes. To this end I have provided a combination of small flexiblemetal tubes so arranged and connected as to deliver a substantial volume of 011 and an envelop for protecting these small tubes, which envelop shall be itself flexible and yet of suflicient strength to withstand any twists or lateral compressions to which it might be subjected in use.

The details of this construction will be more fully described in the specification which follows in which like characters of reference indicate corresponding parts throughout.

In the drawings which form a part of said specification, like characters are used to indicate corresponding parts throughout and in these drawings; Figure 1, is a general'view 40 of .my oil conductor, Fig. 2, is a section of the two ends thereof, and Figs. 3 and 4, end views of the two couplings.

1, is a plurality of small brass tubes of sufliciently light stock to allow them to be readily bent.

3 is a block having perforations theree through into which the ends of the tubes 1 are soldered. The block 3 is located in an internally threaded coupling member At the other end the tubes 1 enter asmnlar block 5 in which they are fastened in a sumlar manner. This block 5 is mounted in an externally threaded coupling member 6 adapted to make connection with an Internally threaded coupling such as 4. The

lings are arranged to be of which the following is a

specifiblocks

3 and 5 are so arranged. inthecouplings as to make a tight joint andthe coup-f tightly united, so that the oil which passes throughthe tube 1 will pass also through the coupling. Outside of the tubes 1 andproperlyattached to the couplings 4 and 5 is an envelop 8 which may be of any suitable material. I find that such an envelop made of canvas and rubber gives complete satisfaction and protects the 5 outside of the tubes against many forms-of m ury.

7 is a spirally wound strip which may be of any suitable metal, but is preferably made of steel or some such stock. This strip 7 is attached to the couplings 4 and 5 and is either embedded in the envelop 8 or wound against either surface.

In use the conductor is-attached through its couplings with the tank atone end, from which theoil-is to be taken and with the torch or other device at its other end to which the oil is to-be conducted. The couplings having been properly adjusted the oilv will pass freely through the plurality of small pipes to supply a proper amount of oil. If itis desired to bendor coil the conductor the small pipes will readily yield and assume the proper position within the envelop. At the same time the s irally wound strip 7 will yield to conform o the bend of the conductor and will at the same time prevent the tubes from being unduly twisted, crushed or kinked.

The number of tubes -may be varied to suit the amount of oil required-to be conducted, the nature of the couplings may be modified to suit conditions and other changes may be made without departing from the spirit of my invention.

- What I therefore claim and-desire to secure by Letters Patent, is

1. A fiexible'oil conductor comprising a plurality of substantially straight flexible solid wall tubes and a non-compressible, non- 100 kinking envelop having a complete normal separation from said tubes and permitting them to have free play therein.

2. A flexible oil conductor comprising a plurality of substantially straight flexible 105 solid wall tubes and a spirally wound envelop having a complete normal separation from said tubes and permitting them to have free play therein.

3. A flexible oil conductor comprising a 110 substantially straight solid wall flexible conducting tube and a non-compressible, nonkinking envelop having a complete normal to have free play therein.

4. A flexible oil conductor comprising a 1 substantially straightsolid wall flexible con- I 1 ducting tube and having a complet a spirally wound envelop separation from said tube and permitting it ture in e normal separation from said tube and permitting it to have free 10 YJOHN RICHARD DONNELLY,
